PROOFS: Use these theorems and others to prove these statements. Theorem 1: The sum of two rational numbers is rational. Theorem 2: The product of two rational numbers is rational. Theorem 3: √ 2 is irrational. Induction: Prove that 6 divides n 3 − n for any n ≥ 0 Use strong induction to prove that every positive integer n can be written as the sum of distinct powers of 2. That is, prove that there exists a set of...
